Question

In spanish When do you use "e" instead of "y"? When do you use "u" instead of "o"?

Answer 1

I honestly don’t know because I honestly don’t know

Answer 2

We use it when the last letter of the word that connects to another ends with i or y, so it doesn't sound bad.

Step-by-step explanation:

Example: Hoy e inicié mis clases.

The same goes for the o, or u. The reason why "u" is used instead of "o" is to avoid a cacophony, which also occurs when saying "o ocho"

It is only to avoid repeating the vowels.
